Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention particularly relates to a display shift method for an electronic device having a small display section.

[Prior art and its problems]

In electronic devices with a small number of display digits, such as small electronic calculators and Ikeratocomputers, if the entire series of data cannot be displayed on the display unit, a part of the data can be displayed in fractions of the number of display digits. ,Key? - By operating the cursor keys provided on the card, the display position of the data was shifted.

However, with such devices, the data display position can only be shifted by one character with one cursor key operation.Therefore, if you want to display data at a position far from the display position, When using K, the cursor keys had to be operated many times, making the operations cumbersome.

[Purpose of the invention]

This invention was made in view of the above circumstances,
It is an object of the present invention to provide a display shift method that allows the display position of display data to be shifted to an arbitrary position with a few key operations. , when displaying this data, the data is shifted in units of the above-mentioned blocks in response to the operation of the 1 key key.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the circuit configuration of the display shift method of the present invention, where 11 is a key gate.
The IC includes a numeric keypad for entering numerical values, alphabet keys for entering alphabetical characters, function keys for specifying calculation details, various symbol keys, etc., as well as memo keys xxx for displaying memo data, and rEXEJ for displaying f programs.
A key 112, a TAB key 113 for shifting display data to the left, and a TAB key 114 for shifting rightward. When this key is used to operate various keys provided in the key 111C, data is input to the CPU 12. The CPU 12 is
The key performs control operations according to data from -P11, and is connected to memory 13, previous address memory 14, address control circuit 15, and memo buffer 16. The memory 13 stores a plurality of memo data, program sentences, etc., and each of the memo data and program sentences is composed of a certain number of characters, for example, 55 characters or less.

It is also assumed that Jin's memo data and program sentences are divided into a plurality of blocks using specified symbols such as ":" and ",". Among the plurality of data statements stored in the memory 13, which one is the key? - One data statement specified by the operation in code 11 is sent to the memo buffer 1 by the CPUJJ.
6 is written. In other words, this memo 9tuhua 16
It also has a data capacity of 55 characters, and addresses from "0" to "54" are assigned to the data area.

Among the data sentences written in this memo buffer 16,
Data for a certain number of characters, for example 12 characters, starting with the character whose address is specified by the address control circuit 15 is
The data is sent to the display buffer 17 via the dart circuit G, which is opened in response to a write signal from the PU 12. This display buffer 17 holds 12 character data to be displayed on the display section 18. Further, the memo buffer 16 transfers one character of character data at the address specified by the address control circuit 15 to the comparison circuit 19 via the dart circuit G2, which is opened in response to a search signal from the CPU 1:t. Enter. The comparison circuit 19 compares the code of this character data with the code of the delimiter symbol inputted from the delimiter symbol code generator 20. If the two codes are the same, a match is sent to the CPU 12. Outputs signal P.

Next kJ: The operation of the above embodiment will be explained with reference to the flowcharts of FIGS. 2 and 3.

FIG. 2 shows the operation control when the memo key 111 is operated. First, select the memo you want to display.

If you operate the 1 memo key 111 after inputting data keywords, etc. with the 11 key, Stella 7'Al
As shown in , 55 characters of specified memo data are read from 1st message 13 and written to memo buffer 16 . Then, in step At*, the address control circuit 15 sends the memo pads 716 to the first address "1".
A signal specifying "0" is input, and according to this signal, 12 digits from address "0" of the memo buffer 16, i.e., the first 12 digits of data from address "11" are sent via P-) circuit G1. is input to the display buffer 711,
It is displayed on the display section 18. In this case, r-) circuit G11
d. The write signal sent from the CPU 12 causes the data from the memo buffer 16 to pass through the display buffer 1711C. Then step Al
As shown in 1, the contents held in the previous address memory 14 are cleared, and the process ends.

Although the case where the expansion memo key 111 is operated has been described above, the same applies to the case where the rEXEJ key 112 is operated. In other words, after specifying the statement number of the program using the 11-key numeric keypad,
When the J key 112 is operated, the program statement with the specified statement number is read from the memory 13 and stored in the memo/shoes 2 file 1.
6JIC is written as well as this memo-muffer I6
The first 12 digits of data corresponding to addresses rOJ to "11" are input to the display buffer 17 and displayed on the display section 18. Then, the contents held in the previous address memory 14 are cleared, and the process ends.

, FIG. 3 shows the data displayed on the display section 18 by TAB
key, that is, “←” key 113 or “→” key 114
This shows the operation control when shifting by manipulating .First, in step Bll, the address specified by the address control circuit 15 is updated. This is the operated TAB
If the key is "←" key 113, address control circuit 1
The specified address of 5 is "-1", and the "→" key 11
In the case of 4, "+l" is similarly applied, and after this address is updated, a search signal is sent from the CPU 12 to the Sidart circuit G2 in step B1. As a result, the f-) circuit G2 is in the open state. ), the code of the character located at the updated address is input to the comparison circuit 19.The comparison circuit 19 combines this character code and the 2 preset code input from the delimiter code generator 20. Compare and judge the delimiter code for data block division - if the two codes are the same, the CPU
Input the coincidence signal P to IJ. As shown in step Bxs, the CPU 12 determines whether or not the character of the address updated in step Bll is a delimiter, depending on the presence or absence of this match signal. If a match signal is input, it means that the shift operation has been completed, so the process proceeds to step B14, and the address specified by the address control circuit 15 at that point is transferred to the previous address memory 14.
and step B1. At Ic, 12 digits of character data starting with the character at the address next to the specified address are sent to the f-) circuit G1, and K is written to the display buffer 18, and the data is written to the display section 17.
to be displayed.

Also, the Stella fB1. , the match signal is sent to the CPU
If 12 is not input, it means that the display shift has not finished yet), proceed to step Big, and proceed to the above-mentioned Stella 7'B! It is determined whether the address updated in l is "54" or "0".

If the address is "54" or "0",
If the current shift operation is not possible, it is not possible to search for a shift position any further, so step 1
As shown at 3ty, the address at the previous time point is read out from the previous address memory 14 and inputted to the address control circuit 15 to display the address at the previous time point. Well, in step B16 above, the address is "54" or "0".
If not, the above-mentioned Stellaf 6nillc is returned, the address is updated again, and the search operation is repeated until the shift position is found.

FIGS. 4 and 5 explain the display shift operation in the above embodiment, and FIG. 4 is for displaying memo data, and FIG. 5 is for displaying program statements.

FIG. 4 (4) shows an example of memo data written in the memo IJ I JIC, r TANAKAJ, r0

IJ is displayed and address "14" is input into the previous address memory 14. Further, when the "←" key 113 is operated, data r 10 PRINT @ABCJ is displayed. Even if the "←" key 113 is operated any further, the display will not change.

In the above embodiment, the display is shifted using the left end of the data 7'o as a reference, but the display may be shifted using the right end as a reference. Further, although the display shift is set in units of data blocks, it is also conceivable to perform the display itself in units of data blocks so that a plurality of data blocks are not displayed at the same time.

〔Effect of the invention〕

As described above, according to the present invention, the display position of data can be changed by a small number of key operations.
Since it is possible to shift in units of tab blocks, it is possible to provide a display shift method that allows easy confirmation of data sentences.
